During an interview on Australian radio station 2Day FM, Cameron was asked whether she found it intimidating to film bikini scenes alongside Kate - famous for her scantily clad Sports Illustrated photo shoots - but the star was quick to dismiss rumours that there was any kind of rivalry between the two of them.

Instead, Cameron had nothing but good things to say about her co-star, explaining: “I wasn't like, 'Oh my God, I am going to be in a bikini and Kate is going to be in a bikini and what is everyone going to think of me'.

"I am 20 years older than her. I am not trying to be her. She is a beautiful woman. We are completely different and I celebrate her.”

The star also admitted that she wouldn’t switch places with her younger co-star, and instead was embracing her forties.

She added: “I don't wish I was 21 anymore. I am very happy to be 41 and I love it. I feel great about my body. I take care of myself. It is important to me.”
